Slides is the perfect slideshow style exhibit format for Columner Deux. It has an adjustable text space setting, the ability to turn image navigation on/off and a very quiet image counter. You can move through images with the use of keyboard arrows. It allows nearly the maximum amount of space possible to display images in either horizontal or vertical orientation.
Not only can you customize the Previous/Next links with CSS and place them anywhere you wish on the page, but you can also customize their text (again with CSS). Plus, if you don't want to see them at all, you can simply click left and right arrows on your keyboard.
Slides is not currently part of core Indexhibit so you will need to download the files at my Github.
